Sample text

As the figure shows, rods and cones are connected with one another and with higher-level cells by means of horizontal, bipolar, and amacrine cells. The latter three types of cells can either enhance or inhibit the re­ sponse of the cells to which they are connected-a fact of the greatest importance for vision in general and for color vision in particular. At the far end of the retina's information-processing chain are the gan­ glion cells, whose output is sent up the optic nerve to the brain. The net result of these complicated interconnections is that, first, a recep­ tor's output can alter the effects of the outputs of its neighboring re­ ceptors; second, every receptor is connected to several ganglion cells; and, third, every ganglion cell is connected to several receptors.

So here redness, greenness, and yellowness are all zero . What the subject sees is a blue without any other chromatic component-a uni q ue blue, as it is called in the trade. Unique blue is an instance of the phenomenally simple hues to which Hering called attention. The next axis crossing is at 500 nm, where the yellow-blue system is in neutral balance, but the red-green system is in a negative state. This is the locus of the 37 COLOR PERCEPTION AND SCIENCE subject's unique green. At 577 nm, the red-green system is in balance once more, and the yellow-blue system is in a positive state.

It cannot serve to differentiate wavelength changes from intensity changes, since any wavelength difference (be­ tween 500 nm and 550 nm, say) that would make itself known by a difference in the strength of the receptor's output could be simulated for the organism in question by a difference in intensity in the ab­ sence of a wavelength difference . Compare this with the situation depicted in (B), in which there are two receptor types with photopig­ ments of different absorbances whose outputs are simply summed.
